vApplication filed March 2, 1910. Serial No. 546,852.

To all whom itma'y concern:

Be it known that I, JOHN R. WEST, a citizen of the United States,residing at Palmer, in the county of Ellis and State of Texas,

have invented certain new and useful Improvements in Cultivators, ofwhichthe following is a specification, reference being had to theaccompanying drawings. My invention relates to improvements incultivators, and more particularly to means for holding or carrying thestandards of cultivator shovels, plows or the like and adjusting themtoward and-from each other.

One object of the invention is to provide improved means for mountingand adjusting shovel or plow carrying standards.

Another object of the invention is to provide a device of this characterwhich may be applied to the beams of ordinary wheeled cultivators,whereby two rows of plants may be effectively plowed or cultivated, andwhereby the eultivator may be used either as a riding or walkingcultivator.

lVith the above andother objects in view,

the invention consists of the novel construc-` tion, combination andarrangement of parts,

hereinafter fully described and claimed, and illustrated in theaccompanying drawings in which Figure 1 is a side elevation of oneembodiment of 'my invention applied to a wheeled cultivator of ordinaryconstruction;

Fig. 2 is a top plan View, the cultivator being indicated in dottedlines; Fig. 3 is an enlarged plan view of one of the carriers forholding and adjusting cultivator shovell standards; Fig. 4 is a sideelevation of the same partly in section; Fig. 5 is a vertical transversesection taken on the plane indicated by the line `5--5 in Fig. 4; Fig. 6is a detail vertical section taken on the plane indicated by the line6-6 in Fig.v 3; and Figs. 7 to 11 inclusive are detail views of parts.

VIn the drawings A denotes an ordinary wheeled cultivator having theusual rearwardly extending, horizontall beams B loosely mounted attheir. forward ends.

My improved holders orcarriers for the standards of cultivator or plowshovels are mounted on the rear portions of the beams B, and each`comprises a transverse body l made preferably hollow or with hollowends to receive slides 2 on the outer extremities of which arestandards. The latter may be ofany form and'construction and may carrycultivator shovels or 'plows 4 or other earthworking devices; and theyare adjusted toward and from each other by shifting the slides 2 aspresently explained. A third standard 5 is provided at the center of therear portion of the body or holder l and carries a suitable shovel orearth-working device 6 so that the shovels 4, 6, are disposed intriangular relation and'plow the ground between two rows of plants, theshovel 6 working in the center of the furrow, while the shovels 4 workclose to the rows of plants. By arranging two of the holders or carrierson the beams B of the cultivator A it will be seen that as the latter isdrawn over one row of plants it will cultivate in effect two rows.

- The slides 2 arc simultaneously shifted toward and from each otherwithin the body 1 by means of two pairs of toggle links 7, 8,

which links have their adjacent ends over-- friction sleeve 15 to whichis connected by means of the bolt or fastening 16 an angular metal clip17 similar to the clip 14. The pivot or bolt 16 has its lower end xed ina slide 18 in the form of a block or plate having its edges engaged withundercut or grooved guide strips 19 secured to the top and rear portionof the body 1. The slide 18 it will be noted will guide the pivot 16 inits forward and rearward movement and thereby cause the pivots 10, andhence the slides 2 to be moved simultaneously in opposite directions andto the same extent. The clips 14, 17, have connected to them shiftingrods `20, 21, the forward ends of which latter are pivotally connectedto an operating lever 22 which may be fulcrumed on any suitable support.The lever 22, however, is preferably mounted on an upright bracket 23clamped to one of the beams B and the rods 20, 21., are pivotallyconnected to it as shown 7 are overlapped' its pivot or fulcrum 26. rlherear ends of the rods 20, 21, are preferablyv adjustably'` united tothe' clips 14, 17, by screw threading them and engaging their threadedportions with nuts 27 provided in said clips, as shown more clearly inFig. 4 of the drawings.v

In order to permit the `cultivator to be used either' as a riding or awalkingl cultivator the lever 22 is made of angular shape and has itslower vertical portion detachably and reversibly mounted on the pivot26, thelatter being preferably in the form of a boltl By mounting thelever in this manner so that it may be reversed, its horizontal portion28 which forms a handle may be turnedto project in either a forward orrearward direction.` YVhen the cultivator 1s to be used as a ridingcultivator the handle \28`is turned to project forwardly so as to' bewithin reach of the operator on the seat ofthe machine as shown injfFig.l, but when. 'the latter' is to be used a's. a walking4 cultivater, thehandle end ,of the lever is turned ina rearward direction as `shown inFig. 2. Any suitable means may be provided for locking'the lever 22 `inadjusted position but.v l preferably employ the usual spring pro-V-jected' dog or pawl 29 which is arranged in the casing' on the-leverand adapted to engage a segmental' series of rackt'eeth 30 provided onthe support on bracket 23. A bell crank 31 is fulcrumed on theintermediate portion of the lever and has one of its arms connected by alink'32 to the pawl 29, andl its otherarmconnected by a link 33 to apivoted hand ieee 34 adjacent the hand grip portionoft clever.

In order to permit the bracket' or support- Y23 to be effectivelysecured to cultivator beams of different sizes and shapes, 'l prov idean improved clamp which has one sect1on 35 formed integral with thebracket 23. This section 35 is' channeled to receiveJ `one side of thebeam` B and it is opposed to atslnnlar channel section 36, the twosections being united to a` clamp upon the beam by U-shaped lts or clips37, which latter pass through openings in the section 35l and notches inflanges on the section-36. If de.-

' sired, filler blocks 38 may be arranged inthe clamp sections 35, 36,`and shaped'to engage the exterior of the beam B,"such f1ller sectionsmay of course, be of any shape accordjinjg tothe cross sectional shapeof the beam.

suitable meansmay be provided for Any `uniting the body or casing 1 ofthe standard (go-carrier to the cultivator beam or any analogous parttof which the invention may be app'hed,bnt in order. to permit it to beapplied to beams of did'erent sizes and shapes .preferably employ animproved sectional socketor clamp composed of two parts 39,

40. The sections 39, 40, have angular'body flange 'of said bracket.

Vthat the bracket 40 may row of plants and the two @sama portions whichare diametricallyopposed to.

each other and channeled to receive the end of the beam B, and ifdesired, the channels of the sections 39, 40, may be provided withfiller blocks 41 suitably shaped to engage the beam. Vertical fasteningbolts 42 pass through the clampv or socket sections 39, 40, and thebeam-B to effectively unite s aid parts, and said sections 39, 40, areunited to the front face of the body or casing 1 by means of bolts orsimilar fastenings 43 which pass through outwardly and oppositelyprojecting apertured flanges 44 formed on the inner or rear ends ofsaid. sections' 39, 40. @ach of the bodies 1 carries an upwardly andrearwardly inclined handle 45, the lower end of which is secured to anangular attaching bracket 46 arranged preferably on the top of the clampsection 39 and secured in po- 'sition by thevertical bolts 42, whichlatter pass through the horizontal base .portion or This constructionpermits the bracket to be detaehed ,when

.broken so thatA a new bracket may be readily substituted lat littleexpense.

The central standard 5 has its rear portion downwardly curved and itsfront end projects forwardly and is bolted or otherwise f detachablysecured at 47 to a channeled rearwardly extending portion of a T-shapedbracket 48, the cross portion of which latter is hereshown as bolted at49 to the rear side of the body 1 although it will be understood beformed integral with said body Cif desired. ,The side stamiards 3 arehere shown as vertically disposed bars bolted or detachably secured'at50 in vertically l channeled i upright heads `51 formed on the outerextremities of the slides 2.

In operation, forwardly through when the cultivator is drawn thev fieldit straddles one roups of shovels or plows carried by the devlces on thebeams B will edectively' cultivate two rows. of

plants. By adjusting the levers 22 the side' shovels or plows 4 of eachgroup may be positioned nearer tolor farther from each other accordingto the width of the space between the ladjacent rows of lplants, and itwill be noted -thatthis adjustment may be eected without vstopping themachine.

When the handles 28 offthe two'levers are:

turned forwardlythe machine maybe used as a riding cultivator,` andwhenturned rearvwardly the chine may cultivator.

While the preferred embodiments of the invention have been shownandalescribedin detail, it Vwill be understood that I do not wish to belimited to the precise construchandles 45 are used and the mat- 4 bethen operated as awalkingtion set forth, since various'changes' in theform,`proportion and arrangement of parts,

20 two last mentioned pivots,

and in the details of lconstruction, may be resorted to within thespirit and scope of the invention. f f

Having thus described the invention, what 1. The combination yofa hollowbody formed with longitudinal slots, a clamping means at the center ofthe body for attaching it to a beam transversely of the latter,

is claimed is:

slide barsarrangedin the ends of the body for longitudinal movement andcarrying at their outer ends earth Working devices, up right pins insaid slide bars and the slots of said body, two pairs of toggle levers.en-

gaged with said lpins whereby the latter Qserve as pivots, two otherpivots uniting` certain of the vtoggle levers, a slide mounte( means atthe center of the body'ifor atta-ch-V ing it to a beam transversely ofthe latter, slide bars arranged in the ends of the body for longitudinalmovement and 'carrying at their outer ends earth working devices,upright pins in said slide bars and the slots vof said body, two pairsof toggle levers engaged with said pins vwhereby the latter `serve aspivots, two other pivots uniting certain of the toggle levers, a slidemounted on the body and carrying one of the last mentioned pivots, abeam engaging clamp, a 1e-v ver mounted'thereon, co-'acting lockingdevices on the lever and clamp and operating rods connected to' thelever last mentioned pivots. v

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.
